Update: Trans works like a dream. Shifts smooth, no slip, no dirty neutral and no noise.
Waiting for a starter right now. It has a nasty short. I suspect it had a slight short that was causing a slow battery drain I couldnt figure out that just now turned into a full on "hot battery start a fire arc" when you take the battery cable off issue.
As much as I love projects, some days I wish I would have just signed some papers and bought a new boat.
